The First Choice in Safety and will Lower Operating Costs
The slack adjuster is the link between the brake chamber or actuator and the brake camshaft. There are two types in today's market, manual and automatic. Both have an adjusting mechanism, providing a means of adjusting for brake lining wear.
Automatic slack adjusters perform the same function as a standard unit, except that it automatically adjusts for lining wear. It does not require periodic manual adjustment, however, the unit does provide for manual adjustment if necessary.
Automatic Slack Adjusters are fast becoming the industry standard because they offer the most reliable and consistent operation. The result is consistent brake adjustment, and optimum brake performance, which increases profits through less downtime and lower operating costs.
There are many different manufactures of automatic slack adjusters on the market today from companies like Haldex, Crewson Brunner, Gunite and Rockwell/Meritor.
